The system — called "SpeedSpike" — figures your average speed between two points, captures an image of your license plate and reports you if you're going faster than the law allows. Oh, and if you're hoping Great Britain's notoriously gray weather will save you, you're out of luck; the system works even when it's cloudy or dark.
SpeedSpike will be tested in two places: the London borough of Southwark, and along the A374 between Torpoint and Anthony in Cornwall. If the trial is successful, the tech may be used to enforce speed limits near schools, to reduce the need for speed bumps, and for "main road enforcement for traffic reduction."
